Hi Shree,
To apply Hanning window and FFT,
X = fft(x .* hanning(24e3));
Here x = column vector of 24e3 samples (hence 1 second).
Then move x to next block with 50% overlap, then do the above line of code again.
After getting all X's, then you can do median.
Yes, there is some code you need to write but hopefully it is not too complicated.
